Virus-resistant Grapevines

In an effort to reduce or even eliminate the use of pesticides which are harmful to the environment and often times have no effect on the virus they are attempting to kill, researchers are working on virus resistant grapevines. Because it takes so long for a grape to properly ripen on the vine b... Read More

Prokaryotes and Eukaryotes Explained

In a recent article I submitted ("It’s time retire the prokaryote"), the authored proposed that most of us don't know what a prokaryote is and in fact the term as a whole is flawed and should be retired by all microbiologists. Since I'm not a microbiologist by trade, he was right, at least on th... Read More

So a group of paleontologists walk into a museum...

Unfortunately, there is no punchline. Turns out what visiting scientists at the North American Paleontological Convention in Cincinnati thought would be a lark by taking a side trip to Kentucky's Creationist Museum turned into a wave of disappointment, sadness and repulsion as the scientists rea...

Methane-producing molecule can also repair DNA

Archaea are single-celled organisms and a domain unto themselves, quite apart from the so called eukaryotes, being bacteria and higher organisms. Many species live under extreme conditions, and carry out unique biochemical processes shared neither with bacteria nor with eukaryotes. Methanogenic ... Read More

Gene Expression of Listeria During Infection in Real Time

"Scientists in Portugal and France managed to follow the patterns of gene expression in food-poisoning bacteria Listeria monocytogenes (L. monocytogenes) live during infection for the first time. The work about to be published in PLoS Pathogens shows how the bacterial genome shifts to better ada... Read More

Are microbiologists with beards a threat to public health?
